1. To show the cursor in a DI_USERCONTROL dialog item, it is also necessary to move the cursor to the necessary position:

   Coord.X=X;
   Coord.Y=Y;
   Info.SendDlgMessage(hDlg,DM_SETCURSORPOS,3,(LONG_PTR)&Coord);
   

   The default cursor position in a DI_USERCONTROL is {-1,-1}.
2. To show a cursor filling the entire character cell under Windows 9x/Me set the high word of Param2 to 99.

// set the cursor of 3rd element as fully filled cell
Info.SendDlgMessage(hDlg,DM_SETCURSORSIZE,3,(LONG_PTR)MAKELONG(1,99));
